TILTING COLTER FOR PLOWS.

SPECIFICATION forming part of Letters Patent No. 556,754, dated March 24, 1896.

Application iiled November 17,1894. Serial No. 529,183. (No model)y To all whom t may concern:

Be it known that we, GEORGE A. JACKSON, Dnvn PERRINE, and ROBERT P. MATTHEWS, citizens of the United States, residing' at Eaton Rapids, in the county of Eaton and State of Michigan, have invented a new and useful Tilting Colter for Plows, of which the following is a specification.

The invention relates to improvements in tilting eolters for plows.

The object of the present invention is to improve the construction of tilting colters, which are adapted to swing upward and forward to permit a stone, stick, root or other impediment to pass between it and the point of the plow to avoid inipeding the progress of the latter, and to provide such a colter which may be readilyY applied to various kinds of plows.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claim hereto appended.

In the drawings, Figure l is a perspective view of a tilting colter constructed in accordance with this invention and shown applied to a plow. 2 is a detail perspective view of the a-ttaclnnentplate. Fig. 3 is a det-ail sectional view illustrating the construction of the keeper and showing the manner of pivoting the shank of the colter therein.

Like numerals of reference indicate correspont'ling parts in all the iigures oi the drawings.

l designates the shank or standard of a colter pivoted centrally of the keeper 2 on a plate 3 and adapted to swing upward and forward to allow a stone, stick, root or other impediment to pass between the colter and the plow without sticking between them and impedingthe progress of the plow. The plate 2S is secured to one side of aplow-bea1n et, and the keeper 2 consists of a tieplate or bar con neeted with the plate 3 by bolts 5 or similar fastening devices and offset from the plate 3 by bosses G to provide an intervening space for the shank or standard of the colter; but ,instead of employing integral bosses C of the plate 3 washers, blocks or the like can he used.

rlhe side edges of the shank, stem or standard l of the colter are beveled, and the swing of the colter is limited buv upper and lower lu gs S, having inner beveled ends conforming to the configuration of the beveled edges of the shank or standard of the colter and i'orining recesses and interlocking with the saine when the colter is in operative position to prevent any twisting or lateral movement of the shank or standard. The upper lug S is located in advance ot the stein, shank or standard l, and the lower one located in rear of the saine. These lugs S are formed integral with the plate and thejyv limit the rearward swing oi the colter and maintain the saine in proper relation with the plowpoint, and at the saine time permit the colter to swing upward and forward to relieve the plow of any obstruction interposed between it and the colter.

The shank l is provided with a longitudinal series of perforations i), any one of which is adapted to receive a fastening' device lO, which pivots the colter to the plowdieani and which enables the colter to be raised or lowered to arrange it at the desired adjustment in proper relation with the plow-point.

It will be seen that the means for mounting the colter pivotally are simple and comparatively inexpensive in construction and adapt the colter to be readily applied to any oi' the various forms of plows.

Changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this in vention.

That we claim is- The combina-tion ot' a plate, designed to be secured to a plowbeam, and provided on its outer face with integral perforated bosses, located at different elevations, the inclined tieplate secured to the bosses by fastening devices arranged in said pertorations, the upper and lower lugs formed integral with the plate and arranged at the front and rear of the tieplate, and having their ad jacent ends inwardly beveled to form recesses7 a eolter pro- In testimony that We claim the foregoing as vided With a shank arranged between the tieour own We have hereto aflixed our signatures plate and the first-mentioned plate and proin the presence of two Witnesses. vided with a series of perforations and hav- T 5 ing its longitudinal edges beveled and fitting in the recesses of the lugs and interloeked ROBERT P MATTHFWS, with them7 and a fastening' device passing through said plates and through a perforation Xlfitnesses: of said shank and forming a pivot for the lat- GEO.
